Update: I want to make it clear that the reviews for this mattress are not organic, they are derived from a financial incentive, which leads me to believe customers are more inclined to submit a positive review in order to secure the partial refund/incentive offered to them. My message to this company is that a good product will speak for itself and generate a positive response naturally. The use of deception is never needed.
Having said that, my positive review stands for now, but subject to change. I wanted a mattress that was specifically soft and comfortable as well as being good to support my spine. After a few nights of sleeping on it I am very happy. The mattress expresses softness yet with stability where it is needed.

This is my 4th purchase of the Marce blanc matress, 1 for every room now!! Very happy with the comfort, quality and price. Recommended purchase from a satisfied buyer. Thank you

This mattress looks stunning and is so comfortable, its held its shape and made sleep time so much better for me, amazing. Its worth a whole lot more money and the service is excellent, after ordering it arrived within 2 days! In the past I have spent thousands of dollars on mattresses and been so disappointed.
